الوصف

The NC7 series AC contactor (hereinafter referred to as “contactor”) is mainly used in the  circuit with an alternating current of 50Hz (or 60Hz), rated operational voltage up to 690V, and  rated operational current up to 620A under the usage category of AC-3/400V; this contactor is mainly used for remotely closing and breaking circuits, and can be combined with an appropriate  thermal overload relay to form a electromagnetic starter so as to protect the circuits likely to  be overloaded in operation; the contactor is well suited for frequently starting and controlling  AC motors.

Standard: IEC60947-4-1

Contactor is divided into AC contactor (voltage AC) and DC contactor (voltage DC), which is used in power, distribution and electric field. The contactor is used to control the main circuit on and off through the control coil. CHINT contactor has a complete range of types, including air type, vacuum type, module type, capacitance type, etc.

Standard: IEC60947-4-1
